RECORD-SHEET FOR THE DlALS 0F WATCHMENS TIME-CLOCKS.

'1.L-'E@IFICATION forming part of Letters Patent No. 344,479, dated June29, 1886.

Application filed March 13, 1886. Serial No. 105,084.

To aZZ whom it may concern.-

Be it known that I, O'r'ro E. HAusEURe, of the city and county of NewYork, in the State of New York, have invented a new and usefulImprovement in Record-Sheets for the Dials of Watchmens Time-Clocks, ofwhich the following is a specification.

The paper dials for watchmens clocks, which are now largely used,consist, severally, of a long narrow strip of paper having the tured bythe watchman, indicating his presonce at the predetermined stations atproper intervals of time. Ordinarily'these dials are gummed upon theback, and for preservation they are pasted upon a reeordsheet or uponthe leaves of a record-book, which has spaces provided for theirreception. As the dial is simply punctured without removing any of thepaper therefrom, the punctures or perforations in it are closed by thepressure necessary to gum the dial to the record sheet, thus renderingit difficult to inspect or read them after they are pasted therein; andthe object of my invention is to bring the punctures in the paper dialinto strong relief or render them clearly visible after the dial hasbeen gummed upon the record-sheet.

In carrying out my invention, instead of securing the gummed dials upona plain space on the record-sheet I apply between the dial and therecord-sheet a soluble ink or color which,when the dial is moistened andgummed upon the sheet, will be partially dissolved and strike throughthe punctures in the dial, so as to render them clearly visible bybringing them into strong contrast with the white surface of the dial.The spaces of the recordsheets which are to receive the dials may havethis soluble ink or coloring-matter applied to them, and when themoistened dial is pressed down on the spaces to which the ink orcoloring-matter is applied the latter will be dissolved or renderedsoluble sufficiently to sltrilkestrongly through the punctures in the 1aThe invention consists in a record-sheet, to which the punctured dialsof a watchmans clock are to be gummed, having a soluble ink orcoloring-matter applied to the spaces for the reception of the dials.

The invention also consists in the combina- (No model.)

tion, with a record-sheet and the punctured dial of a watehmans clockgummed thereto, of a soluble ink or coloring-matter applied between thesheet and dial, so that it will strike through the perforations of thedial.

The accompanying drawing represents a portion of a record-sheetembodying my i11- vention. This sheet A may be considered as the leaf ofa record-book, and it has upon it spaces I), which are to receive thedials after they have been punctured and removed from the clock, inorder that the dials may be preserved for future inspection.

I have here represented a dial, B, as secured upon one of the spaces Z).The backs of the dials are usually gummed or covered with mucilage, sothat by moistening them and pressing them upon the spaces 1) for theirreception they will become firmly affixed to the sheet A.

In puncturing the dials B none of the paper is removed, and the pressurewhich is neces sary when applying the gummed dial upon the sheet pressesthe paper back so as to nearly close the perforations or punctures, andrender them not clearly visible upon the dial. In order to render theseperforations or punctures clearly visible after the dials are pasted onthe sheetI apply between the dial and the sheet a soluble ink orcoloring-matter which, by the moisture applied to the gummed surface,will be sufficiently dissolved so as to strike through the punctures orperforations of the dial, making them clearly visible.

In this example of my invention the soluble ink orcoloring-matter isapplied to the spaces 7) for the reception of the dials as indicated inblack in the drawings.

To secure the dials B to the sheet A, it is only necessary to moistenthe baekof the dial in the usual way and press it down upon the sheet,and the coloring-matter of the spaces b will then be renderedsufficiently soluble, so that it will strike through the punctures, asindicated by black (lots at the top of the drawing, to render the pointsor punctures clearly visible.

By my invention I enable the dials ofwatchinens clocks to be veryclearly read or inspected after they are secured upon the record-sheetor in a record-book, and I provide for this desirable result withoutmaterially increasing the cost of the record-book.

Any ink or coloring-matter which is readily soluble by a little moisturewill answer the purpose. An ink or composition which will satisfy theseconditions may be made by mixing one pound of nut-galls with one quartof water, to Which is added four ounces of sulphate of iron dissolved,and also one-half an ounce of bichromate of potassa. To this mixture addfour ounces of gum dextrimand boil until the composition is of properconsistency.

\Vhat I claim as my invention,and desire to secure by Letters Patent,is-

1. A record-sheet to which the punctured dials of a watchmans clock areto be gummed,
